Add "maint check xml-descriptions" to test builtin xml target descriptions
Now, GDB is able to dynamically create i386-linux target descriptions from features, instead of using pre-generated target descriptions. These pre-generated target descriptions are no longer used by GDB (note that they are still used by GDBserver). This patch add a new maint command "maint check xml-descriptions" to test dynamically generated tdesc are identical to these generated from xml files. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * cli/cli-cmds.c (maintenancechecklist): New variable. * gdbcmd.h (maintenancechecklist): Declare it. * i386-linux-tdep.c (_initialize_i386_linux_tdep) [GDB_SELF_TEST]: Call i386_linux_read_description with different masks. * maint.c (maintenance_check_command): New function. (_initialize_maint_cmds): Call add_prefix_cmd. * target-descriptions.c (tdesc_reg): override operator != and ==. (tdesc_type): Likewise. (tdesc_feature): Likewise. (target_desc): Likewise. [GDB_SELF_TEST] (selftests::record_xml_tdesc): New function. (maintenance_check_xml_descriptions): New function. (_initialize_target_descriptions) Add command "xml-descriptions". * target-descriptions.h (selftests::record_xml_tdesc): Declare. gdb/testsuite: 2017-07-26 Yao Qi <yao.qi@linaro.org> * gdb.gdb/unittest.exp: Invoke command "maintenance check xml-descriptions". gdb/doc: 2017-07-26 Yao Qi <yao.qi@linaro.org> * gdb.texinfo (Maintenance Commands): Document command "maint check xml-descriptions".
